A Preliminary Study On The Status And Risk Factors Of Work-related Musculoskeletal Disorders Among Workers In Construction Industry

BackgroundOccupational musculoskeletal disorders(Work-related musculoskeletal disorders,WMSDs)were a common work-related disease,which brings about great harm and wide range.There were urgent problems to be solved worldwide.At present,our research on WMSDs was mainly concentrated in the automotive and healthcare industries,and there was little research on the construction industry.ObjectiveTo investigate the prevalence of occupational musculoskeletal disorders(WMSDs)of construction industry personnel,analyze and discuss their related risk factors and influencing factors,and provide a scientific basis for preventing and controlling the occurrence of WMSDs.MethodsThis study used an epidemiological cross-sectional survey method and selected the electronic version of the "Musculoskeletal Disorders Questionnaire(Chinese Version)" to investigate the occurrence of WMSDs in 290 staff members of a construction company in Guangzhou in the past 1 year.According to the questionnaire The data obtained from the survey used chi-square test and Logistic regression analysis to explore the influencing factors of WMSDs in the construction industry.Results(1)Basic situation: A total of 330 questionnaires were distributed in this survey.After verification and screening,290 valid questionnaires were obtained with an effective recovery rate of 87.9%.There are 264 men and 26 women in the construction industry,with an average age of 41 ± 10 years.(2)The prevalence of WMSDs among construction workers: Among the 290 valid questionnaires obtained,the prevalence of WMSDs among staff reached 53.8%,and the annual incidence of WMSDs in different parts of the body fluctuated between 4.5% and 32.8% The order was lower back(32.8%),shoulder(27.6%)and neck(20.3%).The prevalence of upper back(16.9%)and wrist(16.9%)was above 10%,and the elbow(4.5 %),Legs(5.9%),knees(5.2%)and ankles(8.6%)were less than 10% prevalent.(3)Risk factors: The results of chi-square test and multivariate logistic regression analysis showed that the risk factors for the occurrence of WMSDs in the neck were: repeated operations per minute(OR = 2.36),staff shortage(OR = 1.98),and the neck remained in the same posture for a long time(OR = 1.91),maintain knee flexion posture for a long time(OR = 2.03);risk factors for WMSDs on shoulders are: carrying heavy objects greater than 5kg(OR = 1.55),degree of neck flexion(OR = 1.59),neck long time Maintain the same posture(OR = 3.78),whether you can change the posture of the legs during work(OR = 3.33);the risk factors for the occurrence of WMSDs in the lower back were: repeated operations per minute(OR = 2.68),handling heavy objects greater than 5kg(OR = 1.46),frequent overtime work(OR = 1.77),degree of back flexion(OR = 2.02),long-term stooping posture(OR = 2.75),long-term stooping posture(OR = 2.12).In addition,adequate rest time(OR = 0.33)and colleagues taking turns to complete tasks(OR = 0.39)are protective factors for shoulder WMSDs.ConclusionsThe prevalence of WMSDs in the construction industry is relatively high,and it is concentrated on the neck,shoulders,lower back and other parts.Squat leg posture,neck flexion,and neck staying in the same posture for a long time were risk factors for WMSDs in the construction industry.Sufficient rest time and taking turns to complete tasks with colleagues are protective factors for WMSDs in the construction industry...
